Circle Hunt Around the Room

Students hunt for clock faces, cups, lids, coins, plates and other circles, measure across the center and calculate the circumference. They may use a calculator, and they use the same unit for every measurement.

Two pages. Page 1 shows a circle labeled circumference, radius and diameter, 4 steps for measuring, a worked example for a plate with a 20 cm diameter that comes to about 62.8 cm around, and a list of places to look. Page 2, My Circle Hunt, is a table with columns for the circle found, the diameter, 3.14 times the diameter and a string check.

Yes. We made it for 5th Grade holiday activities, and it works the same at home or at school. Families print it for one child and keep it where they will use it every day. Teachers print a copy per student or one for the whole room, whichever the day needs.

2 printable resources, all free to preview. There are 25 Pi Day resources in all, from Kindergarten to 5th Grade, gathered on our Pi Day activities page. Downloads are included with a ClassWeekly free trial, and every page prints on standard 8.5 x 11 paper.

These are written for 5th Grade students, roughly ages 10-11. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.

Yes. Nothing here assumes a classroom of 25, so they work the same one-to-one at the kitchen table as they do in a 5th Grade classroom, a learning center, or a tutoring session.
